Can farms produce enough food to feed us while still leaving space for wildlife? A new proposal says they can.



By setting aside one-fifth of farmland for nature, and tweaking everyday practices on the rest, we can help wildlife recover without sacrificing the food on our tables.



<h2 class="wp-block-heading" id="h-farming-with-wildlife-in-mind">Farming with wildlife in mind</h2>



The plan comes from ecologists at the <a href="https://www.ceh.ac.uk/">UK Centre for Ecology &amp; Hydrology</a> and the University of Alcalá in Spain. Study co-author Professor James Bullock elaborated on the importance of the research.



“Reversing <a href="https://www.earth.com/news/un-report-calls-for-global-change-to-stop-biodiversity-loss/">biodiversity loss</a> and degradation of ecosystems is essential both for nature as well as long-term global food security. But there is no single silver bullet for nature recovery and so far it has been unclear how to integrate rewilding into agricultural landscapes," said Professor Bullock. 



“Our proposed approach moves beyond land sparing versus land sharing. We believe rewilding can be interwoven into agricultural landscapes and could be key to maintaining <a href="https://www.earth.com/news/increasing-plant-based-food-production-would-have-extremely-positive-impact/">food production</a> in a way that is sustainable in the long term for people and the planet.”



<h2 class="wp-block-heading" id="h-dedicating-land-to-nature-recovery">Dedicating land to nature recovery</h2>



According to the study, fostering rewilding approaches alongside farming could create agroecological landscapes that accommodate biodiversity while remaining resilient and functionally connected. Certain incentives would encourage farmers to adopt this approach.



“While setting aside land for nature recovery could potentially be made a legal requirement for farmers and landowners, there is more likely to be acceptance and success of rewilding if there are incentives in the form of payments for ecosystem services and tax deductions,” noted Professor José María Rey Benayas, lead author on the study.



<h2 class="wp-block-heading" id="h-why-farming-needs-wildlife">Why farming needs wildlife</h2>



Modern farming has greatly increased food production since the 1940s. But this has often come at the expense of nature. 



Clearing land, using heavy fertilizers and pesticides, and removing natural features like hedgerows have pushed many plant and animal species to the edge.



This loss doesn’t just affect wildlife - it disrupts vital services that farms depend on, such as healthy soil, natural pest control, and water retention. As these services decline, the long-term productivity and resilience of farming systems are put at risk.



<h2 class="wp-block-heading" id="h-the-cost-of-declining-wildlife">The cost of declining wildlife</h2>



Across Europe and beyond, once-common species are disappearing from farmland. For example, the U.K. has lost over 40 million birds since 1970, and wild bee populations have declined in more than half of European countries, according to multiple long-term surveys.



These animals aren’t just part of the scenery - they’re key to food production. Birds eat crop pests. Bees and other insects pollinate the flowers that develop into fruits and vegetables. Their loss means greater reliance on artificial fertilisers, pesticides, and expensive manual labour.



Bringing wildlife back isn’t just a conservation goal - it’s a practical step toward more affordable and reliable <a href="https://www.earth.com/news/mixed-cover-crops-may-be-the-future-of-sustainable-farming/">farming</a>.



<h2 class="wp-block-heading" id="h-steps-to-farming-alongside-wildlife">Steps to farming alongside wildlife </h2>



The researchers suggest a four-part plan that links nature conservation with everyday farming. 



First, they recommend reserving at least 20% of farmland for nature. This space would include large patches of woodland, wetlands, and species-rich grassland to form strong core habitats. 



Second, these patches should be connected by green corridors - such as hedgerows, ponds, and strips of scrubland - that allow wildlife to move, feed, and reproduce.



Third, they propose protecting small hotspots within working fields. This would involve setting aside about 10% of cropped land for flower strips, beetle banks, and bird perches, bringing the total to the 30% global restoration goal. 



Finally, they call for small changes in daily farming practices, like reducing chemical use, planting flowers for <a href="https://www.earth.com/news/pollinators-face-extinction-risk-due-to-climate-change/">pollinators</a>, and letting livestock graze more freely to help spread seeds and support healthy soil.



<h2 class="wp-block-heading" id="h-rewilding-has-benefits-for-farmers">Rewilding has benefits for farmers</h2>



Many European regions cannot host bears or bison. However, smaller species such as lynx, wildcat, or European hare can still boost ecosystem health. Choosing the right mix depends on local conditions.



Helping wildlife can pay off in more ways than one. When farms support natural habitats, they often see practical benefits in return. 



Better soil retains more water and nutrients, which supports stronger <a href="https://www.earth.com/news/farmers-can-help-make-crops-more-resilient/">crops</a>. Pollinators and natural predators of pests can help increase yields in nearby fields. 



Farmers may also spend less on fertilizers and pesticides, lowering overall input costs. In some places, governments might provide payments or tax breaks to reward efforts that support biodiversity and ecosystem services.



<h2 class="wp-block-heading" id="h-making-room-for-wildlife">Making room for wildlife</h2>



Reaching the 20% target may be challenging for small farms, but collective action can make it achievable. At the same time, each region will need to adapt the plan to fit its local conditions. 



Areas with heavily degraded farmland have the most to gain, while places with traditional, low-impact farming may require fewer changes. 



The researchers emphasize that this is just a starting point - but the message is clear: making room for wildlife alongside farming can help secure both indigenous species and food for the future.

Farming for wildlife: How traditional practices can protect nature

Can farms produce enough food to feed us while still leaving space for wildlife? A new proposal says they can. By setting aside one-fifth of farmland for nature, and tweaking everyday practices on the rest, we can help wildlife recover without sacrificing the food on our tables. Farming with wildlife in mind The plan comes from ecologists at the UK Centre for Ecology &amp; Hydrology and the University of Alcalá in Spain. Study co-author Professor James Bullock elaborated on the importance of the research. “Reversing biodiversity loss...

A new study has found that <a href="https://www.earth.com/news/indigenous-knowledge-can-help-protect-amazon-wildlife/">indigenous</a> people in the rainforests of Gabon have more knowledge about plant and fruit-eating animals (frugivore) interactions than that found in academic sources. On average, indigenous people in Doussala, Gabon knew about 732 different plant and frugivore interactions, covering 100 frugivores ranging from elephants to bats, and 286 plant species. Astonishingly, some locals were able to identify up to 2,700 interactions.



When comparing this Indigenous knowledge with information found in academic literature, the researchers found that 34 percent of these interactions were known only by local people, 22 percent were unique to academic sources, and 44 percent were shared between the two.



&nbsp;“Comparing knowledge from local people with academic knowledge from literature, we found that even though many interactions were known by both, local people were the most knowledgeable,” said study lead author Clémentine Durand-Bessart, a PhD researcher at <a href="https://biogeosciences.u-bourgogne.fr/en/home-page">Biogéosciences Université de Bourgogne</a> and <a href="https://cesco.mnhn.fr/fr">Centre d'Écologie et des Sciences de la Conservation</a>, France.&nbsp;



“In our two months of fieldwork in Doussala, we obtained as much, if not more information on the diversity of interactions between trees and fruit-eating animals than those obtained (and published) in the academic literature that required decades of work.”



Indigenous knowledge has been historically undervalued. The findings highlight the need for integrating local sources of knowledge with academic literature, in order to fully understand the complexity of ecological networks. This would be particularly valuable in remote locations, where conducting scientific research could be expensive as well as potentially dangerous.



“An important aspect of ecological studies is to gather as much knowledge as possible to have a better view of how ecosystems work. Our study clearly demonstrates that local ecological knowledge, which is often unique, is invaluable to understanding numerous ecological processes, particularly in remote areas,” explained Durand-Bessart.



“The addition of these interactions to those of the academic literature are changing what we know of tree-frugivore interactions and will ultimately help to inform how we protect these species and habitats.”



According to Durand-Bessart, there is an urgent need for a collaborative relationship between scientists and local communities, from which both parties can benefit. “This can be done through valuing local knowledge and compiling the collected knowledge in local dialects. I also think it’s really important to share the feedback from the study to local communities who make this type of research possible.”



This study will be presented at the <a href="https://www.britishecologicalsociety.org/events/ecology-across-borders-2021/">Ecology Across Borders</a> conference in Liverpool, which takes place between 12 and 15 December, 2021.

Throughout history, rivers have transported a large amount of driftwood to the oceans. However, humans all over the globe are increasingly interfering with this process. New research led by <a href="https://www.colostate.edu/">Colorado State University</a> (CSU) has found that disrupting the flow of driftwood from rivers to oceans can have a significant impact on marine ecosystems.



“Dead trees, known as large wood in rivers or driftwood in oceans, have come to be more appreciated since pioneering research in old-growth forests revealed the role of standing and downed dead wood in providing nutrients and habitats to a wide array of organisms,” wrote the study authors.



Driftwood also plays a crucial role when it reaches both freshwater ecosystems, such as those in rivers or lakes, and marine ecosystems. In the open ocean, driftwood provides vital habitat and food sources for a large variety of organisms, including mollusks, fungi, crustaceans, and microbial communities.



“When driftwood sinks, it’s like a sunken coral reef,” said study lead author Ellen Wohl, a fluvial geomorphologist at CSU. “Living creatures, mostly invertebrates, clams and crustaceans use that wood as a refuge.”&nbsp;



During the past few centuries, human activities have significantly reduced wood supply to the oceans by altering each component of production, recruitment, or transport. “We as humans have been altering the wood cascade and interrupting it for more than a century,” said Wohl.



Driftwood is often removed in some coastal areas, such as tourist beaches in the Mediterranean, disregarding its crucial role for a variety of animals and plants, as well as for the movement of sand.



“Small scale human impacts, such as removing wood from a river, draining a floodplain and logging a hillslope, affect the entire river corridor at a much broader scale,” said study co-author Emily Iskin, a doctoral student in the <a href="https://warnercnr.colostate.edu/geosciences/">Department of Geosciences</a> in the Warner College of Natural Resources at CSU. “Everything is connected. Logjams in a river are not only beneficial to that local ecosystem, but also provide benefits downstream all the way to the open ocean.”



Professor Wohl hopes that these findings will increase efforts to measure wood flux to the oceans from the remaining relatively undammed rivers such as the Yukon and the Mackenzie in North America, or the Amazon and the Congo in the tropics, and help reduce humans’ interaction with these essential natural processes.



The study is published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.abj0988">Science Advances</a>.

The <a href="https://www.earth.com/news/omicron-high-transmissibility-and-chance-for-reinfection/">Omicron</a> variant of the coronavirus was first identified in South Africa on November 26, 2021. It has already spread to <a href="https://www.ecdc.europa.eu/en/news-events/epidemiological-update-omicron-data-10-december">62 countries</a> all over the world, and may <a href="https://www.washingtonpost.com/world/europe/omicron-dominant-europe-covid/2021/12/10/7ec14c42-59df-11ec-8396-5552bef55c3c_story.html">become the dominant variant</a> in some European countries by as early as next week.&nbsp;



Omicron does not seem to cause more severe illness. In fact, its symptoms appear to be <a href="https://www.economist.com/graphic-detail/2021/12/11/early-data-on-omicron-show-surging-cases-but-milder-symptoms">milder</a> than those of previous variants. However, its high transmissibility makes experts claim that Omicron will soon become dominant globally, giving rise to enormous waves of infections in most of the world’s countries.



In one of the first peer-reviewed studies about this variant (published in&nbsp;the journal <a href="https://www.tandfonline.com/doi/full/10.1080/22221751.2021.2017757">Emerging Microbes &amp; Infection</a>), a research team led by China’s <a href="http://english.nmpa.gov.cn/2019-07/19/c_389166.htm">National Institutes for Food and Drug Control</a> (NIFDC) has tested 28 serum samples from COVID-19 convalescent patients infected with the original strain of the coronavirus that emerged from Wuhan against in vitro Omicron samples (as well as other variants of concern and interest).&nbsp;



The experts discovered that the neutralization potential of these sera against Omicron decreased 8.4 fold. This reinforces previous <a href="https://www.medrxiv.org/content/10.1101/2021.11.11.21266068v2.full.pdf">findings</a> that argued that Omicron is capable of dodging immunity gained from previous infections.



“We found the large number of mutations of the Omicron variant did cause significant changes of neutralization sensitivity against people who had already had COVID,” said study senior author Youchun Wang, a researcher at NIFDC. “However, the average ED50 (protection level) against Omicron is still higher than the baseline, which indicated there is still some protection effect that can be observed.”



Wang and his colleagues predict that Omicron may be able to evade to a certain degree also vaccine-induced immunity, particularly since real-world data has already shown that the protection from vaccines diminishes significantly four to six months after the second dose.&nbsp;



Pfizer and BioNTech have also <a href="https://www.pfizer.com/news/press-release/press-release-detail/pfizer-and-biontech-provide-update-omicron-variant">reported</a> earlier this week that sera from individuals who received two doses of their vaccine exhibit more than a 25-fold reduction in neutralization titers against the Omicron variant compared to the wild-type virus, and strongly suggested people to get a booster shot.



“Although two doses of the vaccine may still offer protection against severe disease caused by the Omicron strain, it’s clear from these preliminary data that protection is improved with a third dose of our vaccine,” said&nbsp;Albert Bourla, Pfizer’s Chairman and Chief Executive Officer. “Ensuring as many people as possible are fully vaccinated with the first two dose series and a booster remains the best course of action to prevent the spread of COVID-19.”



However, future real-world studies are essential for clarifying Omicron’s ability to evade previously acquired immunity and thus establish the potential global impact of this new variant.&nbsp;

A new study led by the <a href="https://www.idc.ac.il/en/schools/psychology/research/pages/developmental-social-neuroscience.aspx">Center of Developmental Neuroscience</a> at Reichman University, Israel, has found that chemical signals in mothers’ body odor may have a significant role in supporting the development of infants’ social <a href="https://www.earth.com/news/social-isolation-damages-our-brains/">brains</a> and make them capable of interacting with strangers from an early age.



While maternal body odors serve as important safety-promoting and social recognition signals, their role in human brain maturation has been largely unknown. A research team led by Yaara Endevelt-Shapira, a postdoctoral research associate at the Center for Developmental Neuroscience, has recently investigated in more detail the complex role of chemical signals in enhancing infant-adult brain-to-brain synchrony.



The scientists gave 62 mothers a cotton t-shirt each and asked them to use it as a pajama for two consecutive nights before the experiment. In a first stage of the empirical study, the mothers and their infants had electrodes placed on their heads and were seated initially back-to-back, then face-to-face. When they were facing each other, mothers and infants shown higher neural synchrony.



In a second stage of the experiment, 51 of the infants were seated face-to-face with a stranger – a woman with a similar age as their mothers who lived in a nearby area and had an infant of about the same age. While the infants interacted with this woman, they were exposed to either a clean t-shirt or the t-shirt that their mother used.



Infants who were exposed to a clean t-shirt showed a significantly lower inter-brain neural synchrony with the stranger than with their mother. By contrast, those exposed to the t-shirt with their mother’s body odor showed the same degree of neural synchrony with the stranger as with their mother.&nbsp;



These findings suggest that scent preserves a chemical signal of the mother’s presence even in her absence, increasing the infants’ social capabilities and helping them survive in a constantly changing social environment.



“Human mothers use interbrain mechanisms to tune the infant’s social brain, and chemosignals may sustain the transfer of infant sociality from the mother-infant bond to life within social groups,” the authors concluded.



The study is published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.abg6867">Science Advances</a>.

Scientists estimate that globally two out of five plant species are threatened with <a href="https://www.earth.com/news/hundreds-of-dragonfly-species-at-risk-of-extinction/">extinction</a>. Despite this clear trend, there is still much debate over whether species richness is also declining locally. This phenomenon is referred to as the “biodiversity conservation paradox."



An international team of scientists led by <a href="https://www.idiv.de/en/about-idiv.html">iDiv</a> has now taken a closer look at the displacement of rare plants by analyzing a shift in species composition across three habitats. Plant species were examined in mountain summits, woodland understories, and meadows and pastures.&nbsp;



The results show that widely distributed plants which prefer nutrient rich soils are becoming more common, while plants with small ranges requiring low nutrient soils are in decline.&nbsp;



Across the mountain habitats, species numbers are still increasing. However, according to study first author Dr. Ingmar Staude, this may not always be the case. He said that in the long term, species displacement may be expected here too.



The plant species composition analysis was derived from research at 141 study areas spread across 19 countries. The data goes back as far as the 1940s.&nbsp;



The researchers found that the major culprit of species displacement is an increase in soil nutrients such as nitrogen, which is associated with agriculture. Combustion and an increase in soil temperatures are also contributing factors. These additional factors cause the phenomena to be far outside of normal agricultural areas.&nbsp;



“We are witnessing these dynamics unfolding in near-natural habitats, places we’d expect to provide safe havens for specialized species and those of high conservation value," said Dr. Ingmar. "This suggests that the Anthropocene is not stopping at the doors of the few remaining wild areas that we consider protected.”



“The results of the study are not just be seen as an ‘early warning signal,' said study co-author Professor Harold Pauli. "Particularly concerning is that the species change has proceeded in the same direction across strongly differing ecosystems. We, therefore, expect that we are dealing here with a pervasive, large-scale phenomenon.”



Overall, the research highlights the issue of intense agriculture driving local extinction of rare plants. Unfortunately, this problem will only get worse with a growing population that will demand even more agriculture.&nbsp;



The study is published in the journal <a href="https://onlinelibrary.wiley.com/journal/14610248">Ecology Letters</a>.

Scientists from the <a href="https://www.mbari.org/">Monterey Bay Aquarium Research Institute</a> (MBARI) have recently spotted off the Californian coast a very rarely seen giant phantom jellyfish with 32 feet long tentacles. This elusive deep-sea creature was first officially documented in 1899. It has only been spotted 110 times in over 120 years, and has been captured on camera just nine times.&nbsp;



The giant phantom jellyfish (Stygiomedusa gigantea) is one of then largest invertebrate <a href="https://www.earth.com/news/how-predators-have-outsmarted-monarch-butterflies/">predators</a> in the deep-sea ecosystem. It has an umbrella-shaped bell which can be up to 3.3ft wide, and four “paddle-like” arms that can reach a length of 32ft and are used to trap prey. 



This purple-colored creature lives in the depths of the oceans, in regions up to 21,900ft deep. Although it has been spotted only off the coast of the Pacific, in the Gulf of Mexico, and near Japan, scientists believe it resides in all oceans, besides the Arctic. According to the sparse knowledge gathered so far, the giant phantom jellyfish feeds mostly on plankton and a variety of small fish that live deep underwater. However, more than a century after its discovery, not much is known about this strange animal.



“Even now, scientists still know very little about this animal,” the researchers from MBARI said.&nbsp;“The challenges of accessing its deep-water habitat contribute to the relative scarcity of sightings for such a large and broadly distributed species.” The most recent recording was done at a depth of 3,200ft in the Monterey Bay, with the help of an underwater robot.



Before underwater robots, or “remotely operated vehicles” (ROVs), were invented, experts used trawling nets to study creatures such as the giant phantom jellyfish. However, when such animals are captured and brought to the surface, their usually silky-looking frames turn to “gelatinous goo.” Thus, underwater robots remain the best tool to observe this mesmerizing creature in its natural habitat.

Forest animals often benefit from the sloppy eating behavior of monkeys, according to a new study from the <a href="https://www.ku.dk/english/">University of Copenhagen</a>. The researchers found that animals eavesdrop on monkeys while they are eating in hopes of snatching up discarded <a href="https://www.earth.com/news/ants-swap-spit-to-share-food-and-special-fluids/">food</a>.



"Monkeys are messy eaters. After just a few bites of a fruit, they let it fall to the ground. Other species benefit from this habit. But to do so most effectively, they need to know where and when the monkeys are eating. Here, our study demonstrates that mammals use eavesdropping," said study lead author, Linnea W. Havmøller.



The team spent nine months in a rainforest in Panama studying how various types of fruit-eating animals, including coatis and agoutis, listen to capuchin and spider monkeys as they eat in the trees.&nbsp;



When the half-eaten fruit often falls to forest floor below, the researchers discovered that animals are ready to pounce the moment they hear the food hit the ground.



"It is clear that, when terrestrial animals hear monkeys in a tree, they head towards that tree. It’s as if their ears are telescoped, which lets them hear the lunch bell from wherever it’s ringing. This gives them access to food that would otherwise be inaccessible at the time," explained Rasmus W. Havmøller, a postdoctoral researcher at the Natural History Museum of Denmark.



The study authors explained that the eavesdropping strategy is not just a convenient way to get a little extra food for themselves – it can play a vital role for animals. There is a season each year when food becomes very scarce in Panama, and many species must depend on almond trees for the majority of their food, including the groups observed for the study.&nbsp;



"During this season, there is incredibly little to eat in the forest – other than the prodigious quantities of fruit from this one type of tree. However, terrestrial animals can’t access these fruits unless monkeys drop them. For these animals, the eavesdropping method means that they gain access to food in greater quantities and far sooner than the long time it would take if the fruits were left to fall on their own. And during some periods, it is crucial for their food gathering," said Linnea W. Havmøller.



Ramus W. Havmøller said that in the bigger picture, this means that in areas where monkeys have been removed from the local environment, there can be a negative cascading effect. "Not only will the species of mammals which depend on the fruit being dropped by monkeys suffer – there can be an impact on the entire rainforest ecosystem because terrestrial fruit-eating animals help disperse the seeds that allow the forest to reproduce."



For the investigation, the researchers collected data using GPS collars, cameras, speakers playing monkey sounds, and traps that collected fallen fruit. The analysis revealed that over 90 percent of the fruit which landed in the traps had bite marks and was half-eaten by monkeys. The fruit that fell outside of the traps was eaten almost immediately.



“I think we've underestimated how much mammals interact with each other and how many ways they're actually connected," said Rasmus Havmøller. "Eavesdropping between species is a new chapter in the behavioral biology of mammals, which provides us with important knowledge about how much the disappearance of one species can impact an entire ecosystem."



The study is published in the journal <a href="https://onlinelibrary.wiley.com/journal/17447429">Biotropica</a>.

Through an analysis of fossil footprint tracks, a new study led by the <a href="https://www.unirioja.es/">University of La Rioja</a> has found that, about 100 million years ago in what is now La Rioja province in northern Spain, two bipedal meat-eating <a href="https://www.earth.com/news/two-new-predatory-dinosaurs-found-on-the-isle-of-wight/">theropods</a> reached running speeds of almost 45 kilometers per hour.



About 35 years ago, researchers discovered a few three-toed dinosaur footprints in La Rioja. Recently, further excavations at the site revealed more prints forming two short trails. The analysis of the footprints suggest that they were made by two medium-sized dinosaurs, each about four to five meters long and two meters tall, belonging to either the spinosaur or the carcharodontosaur family of predatory therapods.&nbsp;



By analyzing the distance between consecutive footprints (the stride length), a research team from the University of La Rioja has found that the two dinosaurs were incredibly fast, reaching speeds of up to 45 kilometers per hour. Moreover, abrupt changes in speed suggested that the creatures switched directions as they ran.



“High-velocity trackways are very scarce around the world,” said study senior author <a href="https://www.researchgate.net/profile/Angelica-Torices">Angélica Torices</a>, a paleontologist at the University of La Rioja. According to her, speed helped these dinosaurs not only in hunting, but also in fleeing danger such as "bigger theropods that could see them as their prey."



"Their capacity to run very quickly and their maneuvering abilities surely allowed them to chase prey very efficiently. And of course I wouldn't like to be caught by this guy on a riverbank," added study lead author Pablo Navarro-Lorbes, a doctoral student at the same university.



"There are several factors that dictate the running ability of a dinosaur," Navarro-Lorbes explained. "One of them is size. Some paleontologists think that theropods with sizes between 100 and 1,000 kilograms (220-2,200 pounds) could have been some of the best dinosaur runners because of the relationship between their weight and muscular performance.” Another factor is the dinosaurs’ elongated legs, which was of crucial importance for allowing them reach such speeds.



Further research is needed to clarify the precise mechanics characterizing these theropods’ movements, as well as their relations with other animal species with which they shared their environment.



The study is published in the journal <a href="https://www.nature.com/articles/s41598-021-02557-9">Nature Scientific Reports</a>.

Turkish ichthyologists have made an amazing discovery of the critically endangered Batman River Loach, which had last been seen in 1974. In fact, this is the first <a href="https://www.earth.com/news/fish-protect-corals-by-feeding-on-crown-of-thorns-starfish/">fish</a> to be found as part of a more ambitious plan. 



Nonprofit organizations Shoal and Re:Wild have teamed up to create a top 10 most wanted lost fishes list. The Batman RIver Loach is the first on this list to be found after the project launched in June 2021.&nbsp;



"When I first heard about the Search for the Lost Fishes project, I was very happy," said Cüynet Kaya, associate professor with Recep Tayyip Erdogan University in Turkey.



"Moreover, two of the 10 most wanted fish species were distributed in my country. It is a very different feeling when you see naturalists from foreign countries caring about an endemic species in your country and making efforts to save it."&nbsp;



"As a freshwater fish taxonomist, I thought that I should do my best for this project, and fortunately our efforts resulted in finding the first lost endemic and critically endangered Batman River loach.”&nbsp;



The Batman River Loach is the smallest loach in the Middle East. With a length of approximately 1.4 inches, it is smaller than any loaches in Europe.&nbsp;



Scientists had previously searched in the last known locations for the loach but to no avail. Kaya and Münevver Oral, a research fellow with Recep Tayyip Erdogan University together took a different approach.&nbsp;



The scientists analyzed the possible habitats where the Batman River Loach could survive and searched the Sarim Stream, upstream from the Batman Dam. Using tightly knit nets, they found 14 fish in Sarim Stream. Nine more fish were found in Han Stream.&nbsp;



The researchers said the population of fish seems stable but they worry about the impact of pollution, drought and invasive species. Such a small number of fish is inherently a fragile population.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

<a href="https://www.earth.com/news/dogs-and-infants-recognize-words-using-similar-brain-regions/">Infants</a> may seem to have weak and vulnerable immune systems, but researchers have now demonstrated that this is simply not the case. A new study from <a href="https://www.cuimc.columbia.edu/">Columbia University Irving Medical Center</a> reveals that when it comes to new viruses, babies have stronger immune systems than adults. 



According to the experts, the infant immune system beats the adult immune system at fighting off new pathogens. The research may explain why infants are less affected by COVID-19.



Dr. Donna Farber, a professor of Microbiology &amp; Immunology, explained that while babies are more prone to respiratory illnesses compared to adults, the difference is that babies are seeing these viruses for the first time.&nbsp;



“Adults don’t get sick as often because we’ve recorded memories of these viruses that protect us, whereas everything the baby encounters is new to them," said Dr. Farber.



For the investigation, the researchers tested the immune system’s ability to respond to a new pathogen. They collected naïve T cells, which are immune cells that have never encountered a pathogen, from both infant and adult mice. These cells were administered to an adult mouse infected with a virus.



When the cells competed to eradicate the virus, the infant T cells won by a landslide. The experts report that naïve T cells from infant mice detected the virus earlier (at lower levels), proliferated faster, and traveled in greater numbers to the site of infection - rapidly building a strong defense against the virus.&nbsp;



In a lab experiment, the T cells of human infants performed just as well against adult T cells. “We were looking at naïve T cells that have never been activated, so it was a surprise that they behaved differently based on age,” said Dr. Farber.



"What this is saying is that the infant’s immune system is robust, it's efficient, and it can get rid of pathogens in early life. In some ways, it may be even better than the adult immune system, since it’s designed to respond to a multitude of new pathogens.”



"SARS-CoV-2 is new to absolutely everybody, so we’re now seeing a natural, side-by-side comparison of the adult and infant immune system. And the kids are doing much better."



"Adults faced with a novel pathogen are slower to react. That gives the virus a chance to replicate more, and that’s when you get sick.”



The study results also help to clarify why vaccines are more effective in childhood, when T cells are very robust. “That is the time to get vaccines and you shouldn't worry about getting multiple vaccines in that window,” said Dr. Farber. “Any child living in the world, particularly before we started wearing masks, is exposed to a huge number of new antigens every day. They’re already handling multiple exposures.”



“Most vaccine formulations and doses are the same for all ages, but understanding the distinct immune responses in childhood suggests we can use lower doses for children and could help us design vaccines that are more effective for this age group."



The study is published in the journal <a href="https://www.science.org/journal/sciimmunol">Science Immunology</a>.

Infants have surprisingly strong immune systems

Infants may seem to have weak and vulnerable immune systems,...

Have you ever wondered why adults talk differently to babies than they do to other adults, or even <a href="https://www.earth.com/news/toddlers-chimps-share-gestures/">toddlers</a>? They use a higher pitch than normal, speak more slowly, emphasize or exaggerate certain words and use a different vocabulary. This “baby talk” is not only cute and engaging, but may also be helping infants learn how to produce speech.&nbsp;



New research from the <a href="https://www.ufl.edu/">University of Florida</a> suggests that baby talk, apart from being very effective at getting a baby’s attention, can also have another, previously unknown benefit: it helps babies learn to produce their own sounds and words. The researchers think that using baby talk guides infants in how their own words should sound.



"It seems to stimulate motor production of speech, not just the perception of speech. It's not just goo-goo ga-ga," said Dr. Matthew Masapollo, director of the UF Laboratory for the Study of Cognition, Action, and Perception of Speech.



In the study, the researchers changed the frequency of conversational sounds to mimic either an infant or adult vocal tract. When they tested how infants reacted to each sound tract, they found that six- to eight-month-old babies “displayed a robust and distinct preference for speech with resonances specifying a vocal tract that is similar in size and length to their own.”&nbsp;



By contrast, younger babies of four to six months in age didn’t have that preference. It seems that older babies have already developed some control over their voices and their ability to make “babble words” and this makes the sounds of an adult’s baby talk more interesting and appealing to them.&nbsp;&nbsp;



It is tempting to think of baby talk as a simple form of communication, but that is not necessarily true. For example, words like “choo-choo-train” and “kitty-cat” are actually more complex than their adult language counterparts. Using baby talk clearly has other important functions as well.&nbsp;



Though baby talk may sound simple, it's accomplishing a lot, said study co-author Dr. Linda Polka McGill University.&nbsp;



"We're trying to engage with the infant to show them something about speech production," she said. "We're priming them to process their own voice."



While parents are sometimes discouraged from engaging in baby talk, the new research shows the patterns associated with that speaking style - which scientists call “infant-directed speech” - could be a key component in helping babies make their own words.



The results of the research were published today in the journal <a href="https://www.tandfonline.com/toc/yslh20/current">Speech, Language and Hearing</a>.

“Baby talk” sets the stage for speech production in infants

By investigating ancient DNA found in soil samples pulled from the Klondike region of the central Yukon territory’s <a href="https://www.earth.com/news/permafrost-melting-may-release-nuclear-waste-into-the-atmosphere/">permafrost</a>, a research team led by the <a href="https://www.mcmaster.ca/">McMaster University</a> in Canada has found that ancestral species such as <a href="https://www.earth.com/news/mammoths-were-wiped-out-by-climate-change-not-humans/">mammoths</a> or wild horses survived thousands of years longer than initially estimated.



The scientists used DNA capture-enrichment technology to isolate and rebuild in great detail the fluctuating animal and plant communities at different time points during the transition from the Pleistocene to the Holocene, an unstable climatic period 11,000 to 14,000 years ago when various species such as mammoths, mastodons, or sabre-toothed cats went extinct.



By analyzing tiny soil samples collected from Canada’s permafrost and containing billions of microscopic genomic sequences from animal and plant species, the researchers managed to shed more light on the status of ancient ecosystems at different historical periods.&nbsp;



They found that although mammoths and horses were already in steep decline before the period of climatic instability marking the passage from the Pleistocene to the Holocene, they did not immediately disappear due to human overhunting as it was initially believed. In fact, the DNA evidence shows that the wooly mammoth and the North American wild horse persisted until about 5,000 years ago – well into the mid-Holocene period.



“The rich data provides a unique window into the population dynamics of megafuana and nuances the discussion around their extinction through more subtle reconstructions of past ecosystems,” said study lead author Hendrik Poinar, an evolutionary geneticist and director of the <a href="https://socialsciences.mcmaster.ca/mcmaster-ancient-dna-centre">McMaster Ancient DNA Centre</a>.



The genetic analyses that the research team performed have also shown a strong continuity between the genomic structures of ancient and contemporary horses. “Although mammoths are gone forever, horses are not,” said study co-author Ross MacPhee, a senior curator at the <a href="https://www.amnh.org/">American Museum of Natural History</a>.&nbsp;



“The horse that lived in the Yukon 5,000 years ago is directly related to the horse species we have today,&nbsp;Equus caballus. Biologically, this makes the horse a native North American mammal, and it should be treated as such.”



The researchers stress the need to collect and archive more permafrost samples, which are at risk of being lost forever due to global warming.



The study is published in the journal <a href="https://www.nature.com/ncomms/">Nature Communications</a>.&nbsp;&nbsp;

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."
